In the early years of this blog, someone commented about bacteria resistance as proof of observing ‘evolution’ in real-time. One thing that gets better over time and that is research, but not answers about evolution rather more question which fits the model of a falsified theory.
Those of us who went to public schools have heard that bacteria supposedly evolves resistance towards modern drug use. Medical studies on bacteria resistance are critical for better future treatments. The more we understand over time, the better! A very common bacterium associated with many health issues and also has been a challenge for medical teams around the world because of its ability to resist modern drugs is Klebsiella pneumoniae. The bacterium is mostly known for pneumonia, and bloodstream infections as well as inflections for wounds and surgical areas.
Researchers from Sandia Labs released their study this month and let me tell you, it’s evolution in name only rather in process. The headline reads as follows: Tracing the evolution of a drug-resistant pathogen. But when one reads this article, there is no evolution going on!
“Using Sandia’s genome sequencing capabilities, Hudson and colleagues Robert Meagher and Kelly Williams, along with former postdoctoral employee Zach Bent, identified several mechanisms that bacteria use to share genes and expand their antibiotic resistance. They found that in some cases, bacteria can receive a new set of genes all at once and in the process become pathogenic.”
“To better understand how the process works, they focused on the large mobile DNAs, such as plasmids, which exist as free DNA circles apart from the bacterial chromosome, and genomic islands, which can splice themselves into the chromosome. These mobile DNAs are major mechanisms for evolution in organisms that lack a true nucleus. Genomic islands and plasmids carry genes that contribute to everything from metabolism to pathogenicity, and move whole clusters of genes all at once between species.”
Where are these mutations and natural selection developing new information that is used for resisting drugs? The article never comments on this. This makes the headlines miss leading and contradictory. However, the subtitle which should have been the headline says this, “Bacteria share genetic material with other bacteria.”
It’s an amazing process but has nothing to do with evolution. This has more to do with intelligent design than randomness. If the information is already there and it’s only being shared, this hardly constitutes evolution in action. So the study proves it’s only evolution by name, not by process. Perhaps one day, there will be drugs which will prohibit or distort the sharing of information process among the bacteria which may render it useless. Thus, making people more healthy :)
